1. Two homozygous strains of white-flowered bluebonnets aremated, the F1 offspring all have white flowers. The F1 plants arecrossed to each other, 126 white-flowered and 33 blue-floweredplants were produced. Which of the following best describes thegenotype of a homozygous blue-flowered plant?
| | A/A; B/B |
| | A/A; b/b |
| | a/a; b/b |
| | A/A; b/b or a/a; b/b |
| | there are not enough data to tell |
2. From the F2 offspring in Question1, you cross two whiteflowered plants to each other. Half of their offspring have whiteflowers and half have blue flowers. What are the genotypes of thetwo white-flowered F2 plants?
| | A/A; B/B and a/a; b/b |
| | A/A; b/b and a/a; B/b |
| | a/a; b/b and A/A; B/b |
| | A/A; b/b and A/a; b/b |
| | there are not enough data to tell |
